dc.descriptionThe amplitude analysis has been performed on the pi0 pi0 final state obtained in the pi- p charge exchange process. The pi0 pi0 scattering amplitudes have been obtained for the S and D waves by the Chew-Low extrapolation and the partial wave analysis. Breit Wigner parameters have been obtained for f0(1370) and f2(1270). I=0 S wave pi0 pi0 scattering phase shift has been obtained below K Kbar threshold. They agree well with the pi+ pi- standard phase shift data below 650GeV and deviate by about 10 degrees from the standard data above 650MeV. They show a different behavior from those of Cason and others. The pi0 pi0 phase shift data have been analyzed by the IA method. Resonance parameters have been obtained to be m_sigma =588 pm 12MeV and Gamma_sigma =281 pm 25MeV with r_c=2.76 pm 0.15GeV^-1. They are excellently in agreement with those obtained in the reanlysis on the pi+ pi- phase shift data.
